Nocturnal electromyographic (EMG) recordings of masseter muscle activity were performed before and after treatment on 10 heavy bruxism subjects. Treatment consisted of giving the subjects an auditory feedback signal during sleep which occurred when they clenched with moderate force. Each subject additionally had to perform an arousal task every time the signal occurred. Nine of 10 subjects demonstrated a significantly decreased EMG activity using a contingent auditory feedback signal, combining it with an arousal task.
